摘要

由于静电相互作用

PyTS溶液与MV

溶液混合后能形成PyTS/MV

基态复合物

由吸收光谱滴定得到其组成成分为11的二聚物;而由荧光光谱滴定得到PyTS/MV

复合物组成成分不仅有11的二聚物

而且还有12的三聚物;由瞬态吸收光谱可观察到MV

、PyT

S+

的瞬态吸收峰

这表明PyTS/MV

复合物被光激发后

发生了由PyTS到MV

的电子转移过程;通过对吸收衰减分析得到PyTS/MV

被光激发后的动力学过程.

Abstract

In PyTS and MV

mixture solution in water

the PyTS/MV

complex can be formed by electrostate interaction between PyTS and MV

. From absorption titration results

the stoichiometry of PyTS/MV

complex is 1:1 dimer. However

the stoichiometries in PyTS/MV

complex have 1:1 dimer and 1:2 trimer from fluorescence titration results

these results indicate that fluorescence titration method is more sensitive than absorption titration. The transient absorption peaks of MV + and PyTS + have been detected using nanosecond transient absorption method

it shows that the electron transfer process from PyTS to MV

occurs when the PyTS/MV

complex was excited. We proposed the dynamic schemes from fit results of absorption decays.
